DIESEL EXHAUST FLUID

When you need to internally clean or prime your DEF containers and equipment, use deionized water to wash them to remove the sediment or any built up deposits you see. The following is a list of do’s and don’ts with DEF. • Don’t let DEF get contaminated by coming in contact with foreign materials. DEF purity needs to be maintained, so it is important that you take caution to avoid contaminating your DEF fluid or your holding tank(s). Failure to do so could lead to costly repairs of your SCR system and increased pollution in the air. • Never put diesel in your DEF tank. • Don’t mix DEF with other fuels, oil, tap water or other liquids. • Keep all your DEF equipment clean and free from getting dirty or dusty. • Only use DEF equipment dedicated to DEF to store or refill DEF. • Store DEF between 12-86 degrees Fahrenheit to ensure optimal shelf life.
